2017-03-02The method_missing removal condition in a76dc04a was wrong.Yukihiro "Matz" Matsumoto
2017-03-02Fix possible stack overflow for `method_missing`; fix #3478Yukihiro "Matz" Matsumoto
Instead of shifting mruby VM stack, we always use CALL_MAXARGS.
2017-03-02Reorganize C++ exceptions; ref #3470Yukihiro "Matz" Matsumoto
There are 3 levels of C++ exception handling: * default - no C++ exception (use setjmp/longjmp) * enable_cxx_exception (use C++ exceptions with C ABI) * enable_cxx_abi (use C++ ABI including exceptions)

2017-02-27Remove default Kernel#method_missing.Yukihiro "Matz" Matsumoto
Internal method_missing works without problems.

2017-02-15Move BasicObject#method_missing to Kernel#method_missing; ref #3417Yukihiro "Matz" Matsumoto
More compatibility to CRuby. Updated tests that assume old mruby behavior.
2017-02-15Prohibit too deep `mrb_funcall()` recursion; ref #3421Yukihiro "Matz" Matsumoto
`mrb_funcall()` recursion can cause stack overflow easily, so recursion depth is now limited to MRB_FUNCALL_DEPTH_MAX, which default value is 512.
2017-02-15Do not funcall() Exception#set_backtrace from runtime.Yukihiro "Matz" Matsumoto
This change reduce flexibility but makes mruby simpler and faster.
2017-02-15Preallocate SystemStackError; ref #3421Yukihiro "Matz" Matsumoto
2017-02-15Avoid calling hook methods if they are not overridden.Yukihiro "Matz" Matsumoto
2017-02-15Use mrb_funcall_argv() instead of mrb_funcall()Yukihiro "Matz" Matsumoto
2017-02-14Do not use mrb_funcall() if Hash#default is not overridden; ref #3421Yukihiro "Matz" Matsumoto
This change reduces the recursion level, but does not solve the stack overflow issue entirely.
2017-02-14Extend mruby stack when keep is bigger than room; fix #3421Yukihiro "Matz" Matsumoto
But #3421 still cause stack overflow error due to infinite recursion. To prevent overflow, we need to add different stack depth check.
2017-02-13Should handle `break` from funcall(); fix #3434Yukihiro "Matz" Matsumoto
This issue was reported by https://hackerone.com/d4nny
2017-02-13Fixed too much value_copy() when block is not given; fix #3440Yukihiro "Matz" Matsumoto

2017-02-11Merge pull request #3451 from dabroz/revert-string-mulYukihiro "Matz" Matsumoto
Revert "Optimization for String#* for 1-byte strings"
2017-02-11Avoid direct return from ecall(); fix #3441Yukihiro "Matz" Matsumoto
There's incompatibility left for mruby. When you return from `ensure` clause, mruby simply ignores the return value. CRuby returns from the method squashing the exception raised. ``` def f no_such_method() # NoMethodError ensure return 22 end p f() # CRuby prints `22` ```
2017-02-11Revert "Optimization for String#* for 1-byte strings"Tomasz Dabrowski
This reverts commit d1bc7caecaf337976351934d5910726106601bd9.
2017-02-11`ecall()` should preserve stack address referenced from ci[1].Yukihiro "Matz" Matsumoto
OP_RETURN accesses ci[1]->stackent that might be broken; fix #3442
2017-02-11String#replace should update s->flags for MRB_STR_NO_UTF.Yukihiro "Matz" Matsumoto
Otherwise String#size may return wrong length; fix #3448

2017-02-08Check if irep is NULL before print_backtrace()Yukihiro "Matz" Matsumoto
According to the valgrind log attached to #3438, proc->body.irep may be NULL in some cases.
2017-02-08Add MRB_TT_PROC check to OP_SUPER as well; fix #3432Yukihiro "Matz" Matsumoto
2017-02-08Check if m->env is NULL before dereferencing it; fix #3436Yukihiro "Matz" Matsumoto
2017-02-08Mark classes referenced from saved backtrace.Yukihiro "Matz" Matsumoto
Maybe related to #3438
2017-02-08Fixed a bug in ci address shifting; fix #3423Yukihiro "Matz" Matsumoto
Dinko Galetic and Denis Kasak reported the issue and the fix. (via https://hackerone.com/dgaletic).
